I think Godard's segment is the best of this quartet: it is a quiet but powerful science-fiction story of the kind "The Twilight Zone" would have aired if that show were half as cerebral as it pretended to be. It reminds me a bit of Chris Marker's "La Jetee." Pasolini's film, by contrast, is of little interest to those of us who aren't tortured ex-Catholics; Rosselini's is pointless and boring; and Gregoretti's is a belabored presentation of a single joke -- and not a particularly funny or insightful joke at that.
